The results for 2006 include the results of certain Stelco subsidiaries (namely Norambar Inc. and Stelfil Ltée plants located in Quebec and the Stelwire Ltd. plant in Ontario), from February 1, 2006. As a result, prior period results are not entirely comparable.

Commenting, Lakshmi N Mittal, Chairman and CEO Mittal Steel Company, said:
“We are delighted to report a very strong set of results for the second quarter, with operating income increasing some 49% compared with the first quarter. This improvement is due to improved market conditions in all three of our main operating regions. As we anticipated in May, the recovery is now underway in Asia resulting into higher selling prices. Additionally, we have delivered a strong performance in Europe, particularly in the Ukraine where synergies are now being delivered, and in America, where costs have been reduced.

“Looking forward, we expect market conditions to continue to improve, driving further growth in shipments and operating income in the third quarter.

“Meanwhile approximately 92% of Arcelor’s equity holders (on a fully diluted basis) have accepted our offer for the company and we are now focused on achieving a successful integration. The underlying fundamentals for the industry in the long-term remain positive and we are very excited about the potential of the Company.”
